so i'm doing a little bit of research/thinking about a project i might do and have run into some questions you guys might be able to help me answer.

is it possible in an iphone app (objective-c) to apply effects to a mic-input live. i've seen quite a few applications in appstore allowing you to record a snippet and then apply various tranforms/sound effects to this. but is it possible to do this without the recording part - so i just can 'speak' and have the voice transformed instantly?
